Ubuntu :: Occasional Flickering Screen And Blanks Connected To LCD TV

May 16, 2010

I just connected my LCD TV to my desktop and now I get two things happening which I didn't get when I used a proper monitor:

the screen scrolls down and sort of flickers every minute or so, plus: every few minutes it goes competely 'blank' i.e. reverts to the blue screen of my TV when there is no signal.

It should be in Ubuntu NOT Kubuntu!

Ubuntu Installation :: Occasional Screen Distortion?

May 3, 2010

I upgraded via the terminal from 9.10 to 10.04 and after the upgrade I've been having these weird horizontal screen distortions. I was wondering if there will be a fix to this, and if I'm the only one experiencing this.

Ubuntu :: Screen Blanks - Computer Still On ?

Jul 17, 2010

We have a computer, was windows, we installed ubuntu. It worked well for several months, but once in a while the screen would blank out. The computer was still on, the lights on the computer box are still on, but I can't get the screen to show anything. In the last couple of days, it now does this a couple of times a day. I have to hit the computer off switch, do a shut down, and reboot.

Any particular set of keys I can switch to get the screen to go back on? Like ctrl alt delete?

Also, how do I check the computer to see if there are any problems with the computer? There is system, system testing, does that check the hard drive, start up sequence, anything else? What else can I use to test the computer, system.

Ubuntu :: Screen Blanks After 10 Minutes?

Dec 14, 2010

Since upgrading to 11.04, my screen goes blank if I am not active for 10 mins. This is really annoying if I'm sat on the sofa watching a movie through the computer!

The screensaver is set to 1 hour and the power management settings are set to 'never'. I never had this problem with the previous Ubuntu version. I'm on a desktop rather than a laptop.

Ubuntu :: Screen Blanks And Comes Again When Starting Movie Player

Jan 14, 2011

When I start the Movie Player (Applications -> Sound and Video -> Movie Player), the screen blanks out and then restores again before playing the movie.

I don't see this issue with RhythmBox though. Only the Totem Movie Player seems to be experiencing this issue.

Security :: GDM3 - Screen Blanks Out After Few Inactive Minutes

May 16, 2011

My debian squeeze + testing + unstable came with gdm3.
After setting in /etc/gdm3/daemon.conf:
AutomaticLoginEnable=true
AutomaticLogin=myname
I don't have to type in my username and password on startup. But after a few inactive minutes the screen blanks out, and I have to type in my password now in order to continue. For me hitting any key would be enough. How can I change that?

Debian Multimedia :: Xscreensaver Blanks Screen While Watching Movies?

Jun 5, 2011

I'm using Debian Squeeze with Fluxbox and I'm having a problem with xscreensaver. I've set to blank screen after 10 minutos of inactivity, but the problem is that when I'm watching a movie, the screen is blanked after 10 minutes too. So I have to manually kill xscreensaver before starting to see a movie, or I have to move my mouse / press keyboard every 10 minutes to activate the screen again.

I've done some search before posting and I only found something about a SMPlayer's option named "Disable screensaver", but it is already on and it has no effect preventing xscreensaver to work. Here is a screen shoot of my SMPlayer configuration window:

[URL]

Apparently, xscreensaver isn't being able to recognize that another program is running. Could it be related to dbus?

PS: I had a dbus problem when I first upgraded to squeeze, my multimedia keys stoped working in banshee (whenever I clicked to play/pause/next etc, another banshee process was started), but I solved it by adding this line to my ~/.xinitrc: eval "$(dbus-launch --sh-syntax --exit-with-session)"

Ubuntu :: Screen Flickering After Opening Laptop

Jul 30, 2010

Whenever i close and then open the lid of my Compaq nc6220 laptop the screen will flicker when actions are made like moving the mouse, opening a program or typing. This is a known problem for the Intel 915 card and the solution is to disable the RANDR process. The thing is i cannot get to the service managaer and the RANDR doesnt come up in BUM which i installed. Does anyone know how to disable RANDR or any other solutions to this very annoying problem?

Ubuntu :: Flickering Screen And Unable To Install

Jan 16, 2010

I downloaded the 9.10 from the Ubuntu website (not as torrent, but as direct download) and I burnt the ISO image in a CD. I intruduced the CD in the computer where I want to install Ubuntu and I rebooted it. Then the Ubuntu install-try menu appeared. I chose "try" and appeared a white ubuntu logo fading in and out, and then some text that was like the boot up of Ubuntu. In that point, the screen starts flickering every second, and when I push the power-off button of my computer it stops flickering and says something like "you pressed power off - please remove the CD and close the tray", and then the computer shuts down.

The same happens when I choose Install. At the point it appears a progress number (0%) of the file system, the screen starts flickering and the progress it seems it stops, or at less it's extremely slow.My computer it's a bit old but I think that's not the problem. It's a Pentium IV at 3'40Ghz, 1GB of RAM and what seems to have the problem, a Nvidia Quadro 256MB graphics card (I don't know the exact model but if you need it I can find it).

Ubuntu :: Flickering Screen After Fresh Install Of 11.04

May 22, 2011

I did a fresh install of Ubuntu Studio 11.04 on a machine with Vista previously installed. The computer also came with a Personal Media Drive (movable harddisk) of 500GB. The only modification to the HW conf is that I recently added a harddisk of 2 TB that I wanted to install Ubuntu on. (I.e. in total 4 harddisks on the scsi slots)I ran the install cd that I burnt form the iso and I chose the option to manually partition the disks, and I only partitioned the new Harddisk. The installer chose to make some partitions: grub as the boot loader, one ext4 partition of 2 TB and 3.5 GB swap space (and some kb of waste space).

The install cd was readable and the tests that could be performed on the install cd itself and on memory terminated ok, and install seemed to have worked fine. It also discovered the Vista / ntfs partitions. I thought the install would work ok since I had made the new disk the 1st to boot in the HDD boot priority in BIOS setup.

When I rebooted after install I got a blank screen. I then tried with making the Vista HDD the 1st to boot in BIOS, and then I got the GRUB screen with two options for ubuntu two for mem tests and two for the Vista partitions.I found it strange that GRUB would take over, since the grub partition should be on the new lower prioritized HDD in the boot order.When I run the first Vista option everything works. Vista boots. However, when trying to get it to boot either of the ubuntu options I get a flickering screen, in the normal ubuntu boot a white one where the upper third of the screen is more steadily lit up whereas the lower 2/3 is flickering. When booting with failsafe option the color is red/pink instead, but with the same flickering.

Ubuntu Installation :: 10.04 Boot - Constant Screen Flickering

May 18, 2010

When attempting to boot into Ubuntu 10.04, the screen constantly flickers. It'll stay off for about 2-3 seconds, then come back on for <1 second. This constantly occurs. When reaching the main screen (I think), I attempt to move into a TTY terminal, but the flicker continues. I have attempted to reset the X Server, stop the X server, etc., issue remains. The monitor does not turn off during this flickering. I am able to type, obviously.

Here are my system specs:
AMD Athlon 64 X2 Dual (6000+)
2.00 GB RAM
ATI Radeon HD2600 XT (x2, Crossfire)
HP w2207h 22" Monitor, connected via HDMI

I also have VGA inputs on the back of the monitor and can attempt to switch the input, but that requires me to dig through a box looking for a cable, so I figured I'd post this issue first.

Fedora Installation :: Can't Even Install / Too Much Screen Flickering

I've been trying to install Fedora 10 but the screen flickers about once every two seconds (not at set intervals though sometimes 5 seconds sometimes < 1 second).I've been searching around and all posts I've read about hh ave pointed to an nVidia driver bug which would make sense since I have an nVidia card but these were all posted back in summer of '08 so I'm not sure if it is still lingering.

Fedora :: 15 Screen Flickering - Set Up In The Config File?

Jul 7, 2011

I have a problem with the screen flickering on fedora 15 (and lots of other modern distros, eg: ubuntu 10.10 and 11.04 and opensuse 11.4) i think it is something to do with xorg.conf as older linux distros work fine
so i added one using

Code:
Xorg :1 -configure
cp /root/xorg.conf.new /etc/X11/xorg.conf

but i still have a slight flicker. my monitor takes an input at 50-60Hz how do i set that up in the config file or is that not what is causing that? and can somebody recommend me a nice icon set for fedora

I need to add this somewhere Code: ModeLine "1440x900" 106.5 1440 1520 1672 1904 900 903 909 934 +hsync -vsync in the xorg.conf no idea where!

Ubuntu Installation :: Get Stuck At Black Flickering Login Screen?

Mar 10, 2010

so i have been trying to install ubuntu for quite some time now and i have run into a bit of a roadblock.

I have tried to install 9.10 and it installs just fine (the GUI works just fine and everything seemingly goes ok), however when i go to boot it, i get to a flickering screen asking for my username and password (this is not the gnome login screen, it is just a blank black prompt asking for me to login). however, the flickering is inhibiting me from easily entering anything in from my keyboard. Thus, i cannot log in to fix the problem (i cannot enter my password because i dont know if the keys i am entering are being accepted or not). and recovery mode does the same thing.

This happens if i try installing it straight up, or if i install it inside windows. I have tried all kinds of boot options and install options (all that acpi crap) but none of it works.

i even tried installing some of my old copies of ubuntu (8.04), but when i do that the grub cannot load the linux kernel. I have also tried both the 64-bit and the 32-bit versions to no avail.

I am running an ASUS motherboard, AMD quad core x64, dual Nvidia geforce 8600's, 6 gigs of ram, and PLENTY of hard disk space.

I am not a noob to linux at all, but i have never encountered a problem like this and i have no clue how to fix it. Hell, i dont even know how to go about fixing it without logging in.

Debian Multimedia :: Squeeze KDE4 Flickering Screen

Dec 22, 2010

I updated my system as usually. Sadly since then my screen flickers every 10 (or so) seconds. It turns black for like 10ms and then back to whatever it showed before. This behavior occurs after some uptime. Haven't measured the flicker-free time span yet but I guess it starts after 15 to 30 minutes.I'm using a up-to-date Squeeze with KDE4 an the nvidia-driver for me GeForceGo. Interesting thing is: It does not flicker while using fluxbox using same xserver.

Ubuntu Installation :: Blank Flickering Screen While Installing After First Reboot Using Wubi 9.10

Mar 1, 2010

The wubi installer copied files successfully and asked for reboot. After booting into Xubuntu the flashing logo appeared for a minute. And then the screen looked as if it was trying to show something but could not and flickered and then became dark this continued till half an hour and then I pressed Alt+Ctrl+Del.I tried all the modes but to no avail, only the last mode with command line was working. But it was not helpful for me becoz I dont know most of the commands.When I tried "Verbose Mode" as directed by the WubiGuide - Ubuntu Wiki, CTRL+ALT+F2 did not work when the installer stopped.The computer I use is assembled with Intel pentium 4, VIA chipset and Mercury(Kobian) motherboard.

Ubuntu Multimedia :: Screen Distortions/flickering With 3d Apps Ati Radeon Xpress 1100 On Kubuntu 9.04

Jan 12, 2010

i installed kubuntu 9.04 yesterday and updated it with everything that was available, i have ati radeon xpress 1100 and i got everything running fine including kwin effects but i have a small problem i cant figure out how to fix:

When i run glxgears and put any window on top of it, i can still see the 3d gears rolling and i think this same problem is responsible for occasional artifacts on the screen. Its a very minor problem but i would like to see if fixed because i cannot use google earth properly, it seems that any 3d application likes to be focused on the screen, its like they flicker while being overlaid on top of everything.

Also i read the countless threads here complaining about not being able to use fglrx etc because of updated xorg. Well the reason im using 9.04 is because my wireless card alfa awus036h does not work with kernel > 2.6.31 and i have already tried kubuntu 9.10 on this laptop i wasnt having any problem with the display. All the kwin effects ran fine and no distortions of any kind. Seems there is some bug in 9.04.

Jul 13, 2010

I have this situation: I installed F13 on my laptop having an Intel Graphics Media Accelerator. The screen of my laptop was flickering and i did a 'yum update'. The flickering didn't stop, but after suspending the system once, the flickering stops and everything is fine. Now after each reboot i have to suspend the system once for the flickering to stop. Please help.

After discussing in #fedora in freenode, some people asked for these (i'm posting in case you need them too):
